In veterinary medicine, infection control is not just a priority—it’s a necessity. One of the most effective ways to prevent infection is through the sterilization of surgical and procedural instruments. While autoclaving is highly effective at killing harmful microorganisms, what happens after sterilization is just as important. Improper storage can compromise the sterility of instruments, posing serious risks to both patients and staff. This article explores how to properly store sterilized instruments in veterinary clinics to maintain their sterility and ensure the highest standards of hygiene and safety.
Sterilization is only the first step in infection prevention. Once an instrument has been sterilized, it must be stored correctly to remain sterile until the moment it is used. If stored improperly, even fully sterilized instruments can become contaminated through exposure to dust, moisture, air particles, handling, or compromised packaging. In veterinary settings—where animal fur, dander, and high activity levels can increase contamination risk—storage protocols must be especially rigorous.
Veterinary professionals must treat sterilized instruments as vulnerable assets: delicate in terms of sterility, and critical to maintaining patient safety. Therefore, adopting proper storage practices is a cornerstone of any successful infection control program.
Proper storage begins with proper packaging. The right packaging materials act as a physical and microbial barrier that helps maintain sterility over time. Common types of packaging used in veterinary clinics include:
Sterilization Pouches: These are typically made of medical-grade paper and transparent plastic film. They are convenient for visual inspection and are suitable for most instruments. The self-sealing varieties offer a strong seal that helps maintain sterility.
Double-Wrapped Sterile Wraps: Often made of fabric or synthetic material, these wraps are used for surgical packs and bulkier instruments. The double-layer design offers added protection and minimizes contamination during opening.
Rigid Sterilization Containers: These hard-sided boxes are ideal for long-term storage and high-value instruments. When properly sealed, they offer superior protection against physical damage, dust, and airborne contaminants.
Each type of packaging must be properly sealed and checked for defects before autoclaving. Improper sealing or damaged packaging can result in immediate contamination once the autoclave cycle is completed.
Once instruments are sterilized and properly packaged, they must be stored in an environment that protects their sterility. Veterinary clinics should meet the following environmental standards:
Clean and Dust-Free: Storage areas should be regularly cleaned to reduce the risk of dust accumulation. Dust can carry microorganisms that compromise packaging integrity.
Dry and Moisture-Free: Moisture is a leading cause of microbial growth. Instruments must be stored in a dry environment with low humidity. Avoid areas near sinks, autoclaves, or other water sources.
Temperature-Controlled: While specific temperature guidelines vary, most storage areas should be kept between 18°C to 22°C (64°F to 72°F). Avoid locations with wide temperature fluctuations.
Low-Traffic Zones: Store sterilized items in areas that are not frequently accessed or disturbed. High-traffic areas increase the chance of accidental handling and contamination.
Storage cabinets or drawers used for sterilized instruments should be enclosed and, if possible, dedicated solely to sterile supplies.
Handling sterilized instruments—even if packaged—introduces a risk of contamination. Every touch creates the potential for microscopic tears or punctures in the packaging, or the transfer of bacteria through physical contact. Best practices include:
Handle sterilized instruments only when necessary.
Use clean, gloved hands or sterile tongs when moving or retrieving packages.
Avoid placing sterilized packs on contaminated or wet surfaces.
It’s also advisable to store instruments so that they are easily visible and accessible, minimizing the need to move or shift other items to find what you need.
Before using a sterilized instrument, veterinary staff should always inspect the packaging for any signs of compromise. This includes:
Tears, punctures, or abrasions
Water stains or discoloration
Loose or broken seals
Expired dates (if applicable)
Even if the instrument was sterilized recently, compromised packaging renders the sterility void. Instruments in damaged packaging should be immediately set aside for re-cleaning and re-sterilization.
Efficient labeling helps ensure that instruments are used in the correct order and re-sterilized before the packaging integrity declines. Best practices include:
Label each package with the date of sterilization, contents, and, if applicable, an expiration date based on clinic policy or packaging guidelines.
Implement a first-in, first-out (FIFO) system to use older sterilized packs before newer ones.
Use color-changing sterilization indicators to confirm that each package has completed an autoclave cycle.
Maintaining accurate records of sterilization and storage helps clinics stay compliant with regulatory standards and prepares them for audits or inspections.
Veterinary settings present unique challenges for maintaining sterility:
Animal Hair and Dander: These particles can carry bacteria and other contaminants. Make sure sterilized items are kept in separate rooms or cabinets away from treatment and grooming areas.
Unpredictable Environments: Emergency procedures may increase the frequency with which sterile instruments are accessed. In these cases, maintain multiple sets of essential instruments so one set remains untouched and fully sterile.
Frequent Movement: Mobile practices or clinics with limited space may need portable storage. In such cases, rigid containers or specially designed sterile cassettes offer greater protection during transport.
Maintaining the sterility of instruments is not only about effective autoclaving—it's about what happens afterward. Proper storage of sterilized instruments is an essential, often overlooked, component of veterinary infection control. By using high-quality packaging, storing instruments in clean and controlled environments, limiting handling, and following best practices for inspection and labeling, veterinary professionals can uphold the highest standards of hygiene and safety.
